EASA Part 21, Certification of Aircraft and Related Products
Section 01: Organizations & Authorities
Definition
The EASA Implementing Rule (Commission Regulation (EU) No 748/2012, Annex I) that establishes the certification procedures for aircraft, engines, propellers, parts, and appliances, as well as the requirements for design and production organisations. EASA Part 21 is functionally analogous to FAA 14 CFR Part 21 but differs in structure and process, particularly in its reliance on Design Organisation Approval (DOA) and Production Organisation Approval (POA) as the primary approval mechanisms.
